Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of method, system and equipment of high speed downlink packet access dispatching.
Background technology
In mobile communication system, subscriber equipment (UE, User Equipment) has two kinds of basic operational modes: idle pulley and connection mode.The beginning UE that powers on just rests under the idle pulley.After UE finished Radio Resource control (RRC, Radio Resources Control) connection foundation, UE transferred to connection mode from idle pulley.UE exists four kinds of states under the RRC connection mode, these four kinds of states have reflected that rank and UE that UE connects can use any transmission channel.When RRC connected release, UE transferred to idle pulley from connection mode.
Under the RRC connection mode, the state of UE is divided into four kinds: CELL_DCH state, CELL_FACH state, CELL_PCH state, URA_PCH state.These states have defined physical channel kind, measurement and the mobile management task that UE uses, and the action when state transitions takes place.
Under the CELL_FACH state, user's upstream data sends by Random Access Channel (RACH, Random Access Channel).When the user prepares to send data on RACH, need finish once complete random access procedure.Key step is as follows:
1.UE send uplink synchronous code SyncUL to the base station;
2. the base station sends relevant information to the user by physical access channel (FPACH, Fast PhysicalAccess Channel) after receiving SyncUL;
3. after the user receives FPACH, use uplink random to insert physical channel (PRACH, Physical Random Access Channel) according to timing relationship at time corresponding point and send uplink user data to network.
In the R7 of 3GPP system version, time division multiplexing (TDD, Time Division Duplexing) system has introduced up enhancement techniques (HSUPA, High Speed Uplink Packet Access).HSUPA has introduced five new physical channels: strengthen dedicated channel (E-DCH, Enhanced Dedicated Channel) special physical data control channel (E-DPDCH), E-DCH Dedicated Physical Control Channel (E-DPCCH), E-DCH absolute grant channel (E-AGCH), E-DCH relative authorization channel (E-RGCH), E-DCH mixes automatic heavy biography (HARQ, Hybrid-Automatic Repeatre Quest) confirms indicating channel (E-HICH) and two new MAC entities: MAC-e and MAC-es, and the packet scheduling function from radio network controller (RNC, Radio Network Controller) moves down into the base station, realized fast packet scheduling based on the base station, and pass through HARQ, 2ms is wireless short frame and many yards key technologies such as transmission, make the data throughput of up link can reach 5.76Mbit/s, improved the bearing capacity of uplink data business greatly.
When the user is carrying out HSUPA when professional, promptly the user is when the CELL_DCH state, if network does not distribute ascending resource to this user, and this user uplink data amount becomes non-zero from zero, the user will initiate dispatch request to network, and after the network allocation resource, carries out upstream data and send.Correlation step is as follows:
1. the user sends to the base station and strengthens uplink synchronous code SyncUL;
2. base station feedback FPACH;
3. the user uses corresponding enhanced uplink random access channel (E-RUCCH) according to timing relationship constantly in correspondence, sends dispatch request information to the base station;
4. the base station is carried out ascending resource and is distributed according to user's dispatch request information, and by descending E-AGCH channel, the uplink physical channel E-PUCH resource of notifying the user to use;
5. the user on the uplink physical channel E-PUCH resource of distributing, sends to base station with upstream data according to timing relationship;
6. after user uplink data is received in the base station,, use the E-HICH channel that the downlink data reception condition is fed back to the user according to reception condition and timing relationship;
7. if the base station receiving subscriber data is failed, then the user can retransmit; Otherwise can send new data.
In the R8 of 3GPP system version, introduced TDD HSPA enhancement techniques.In the HSPA enhanced system, when the user is under the CELL_FACH state, can use the RACH channel, also can use the E-DCH channel to carry out upstream data and send.
In strengthening the CELL_FACH technology, when the user carries out the upstream data transmission, can how much select upstream data to send the channel type that uses according to upstream traffic.
In realizing process of the present invention, the inventor finds that there is following problem at least in prior art: when the user sends by RACH and E-DCH channel with a kind of upstream data of business is staggered, when the RNC side joint is received this business datum, may cause certain out of order phenomenon.This out of order phenomenon can cause the unnecessary repeating transmission of upstream data, causes the unnecessary waste of ascending physical signal resource, influences customer service speed and influences cell throughout, thereby cause the significant wastage of system resource.

In order to make those skilled in the art better understand the present invention, method of the present invention is elaborated below in conjunction with the drawings and specific embodiments.
Need to prove, for convenience of description, hereinafter MAC-es or MAC-is are expressed as MAC-es/is, MAC-e or MAC-i are expressed as MAC-e/i; MAC-es entity or MAC-is entity list are shown the MAC-es/MAC-is entity, MAC-e entity or MAC-i entity list are shown the MAC-e/MAC-i entity.
In the HSPA enhanced system, when the user is under the CELL_FACH state, can use the RACH channel, also can use the E-DCH channel to carry out upstream data and send.How many users selects upstream data to send the channel type that uses according to upstream traffic.
At first existing process by RACH channel and E-DCH Channel Transmission upstream data is carried out simple declaration below.
As shown in Figure 1, be the mapping relations schematic diagram of user side MAC inter-entity in the prior art, Fig. 2 is the mapping relations schematic diagram of radio network controller in the prior art (RNC, Radio Network Controller) side MAC inter-entity.Wherein, the function of each entity is as follows:
The MAC-d entity is used to handle the data of DCH channel;
The MAC-es entity is used to handle the data of E-DCH channel;
The MAC-is entity is used to handle the E-DCH channel data under the L2 enhancement techniques;
The MAC-c entity is used to handle paging channel (PCH, Paging Channel), forward access channel (FACH, Forward Access Channel), RACH channel data;
MAC-e entity and MAC-i entity all are used to handle the data of E-DCH channel.
The channel type that UE selects upstream data to send to use is during as RACH, and transmission and processing process is as follows:
1.UE the data that will need to send form MAC-c PDU by the MAC-c entity, send to the base station;
2. after MAC-c PDU is received from RACH corresponding physical channel PRACH in the base station, form RACH Frame Protocol (FP, Frame Protocol) Frame and send to RNC;
3.RNC after receiving RACH FP Frame, MAC-c PDU is wherein sent to the MAC-c entity, if Common Control Channel (CCCH, Common Control Channel) data, send to radio resource controller (RRC, Radio Resource Controller); If Dedicated Control Channel (DCCH, Dedicated Control Channel)/Dedicated Traffic Channel (DTCH, Dedicated TrafficChannel) data is submitted to the MAC-d entity handles.
The channel type that UE selects upstream data to send to use is during as E-DCH, and transmission and processing process is as follows:
1.UE the data that will need to send form MAC-es/is PDU by the MAC-es/is entity, and provide corresponding transmission sequence number information such as (TSN, Transmission Sequence Number), are submitted to the MAC-e/i entity then; The MAC-e/i entity is formed MAC-e/iPDU with information such as MAC es/is PDU and TSN, sends to the base station by the enhancing uplink physical channel (E-PUCH) of eating dishes without rice or wine;
2. the base station receives data from eating dishes without rice or wine, and the MAC-e entity is resolved the MAC-e/i PDU that receives, and parses wherein MAC-es/is PDU and information such as TSN, and the EDCH FP Frame of forming Iub mouth (interface between UE and the base station) sends to RNC;
3.RNC after receiving EDCH FP Frame, information such as wherein MAC-is/es PDU and TSN are submitted to the MAC-is/es entity, the MAC-is/es entity sorts to MAC-is/es PDU according to TSN, sorted PDU is resolved, parse MAC-d PDU wherein, be submitted to the MAC-d entity handles.
As seen, because there are following difference in E-DCH channel and RACH channel:
1.E-DCH channel is the interface function that has HARQ to retransmit aloft; The RACH channel should not handled;
2.RNC side has the processing of reordering to the E-DCH data; The RACH channel should not handled;
3.RACH and the Transmission Time Interval (TTI, Transmission Time Interval) of E-DCH different (TTI of RACH is generally 10ms, and the TTI of E-DCH is 5ms).
Thereby can cause the unnecessary repeating transmission of upstream data in the prior art, cause the unnecessary waste of ascending physical signal resource, influence customer service speed and influence cell throughout.
For example, UE sends the data of same business, supposes Radio Link control (RLC, the Radio Link Control) transmission of the affirmation pattern that this business is used, and selects earlier to send data by the E-DCH channel, selects then to send data by the RACH channel.UE selects the E-DCH channel to send data, and corresponding rlc layer RLC PDU sequence number SN is 0-6; UE selects the RACH channel to send data, and corresponding rlc layer RLCPDU sequence number SN is 7.
The network controller side is received the data (because the data of E-DCH channel retransmit) on the RACH channel earlier, and the rlc layer of network controller side thinks that sequence number SN has been the RLC PDU data packet discarding of 0-6, notifies UE to retransmit by the mode of status report; And in subframe subsequently, network controller has been received the data from the E-DCH channel, and correctly having received sequence number SN is the RLC PDU data of 0-6.
UE applies for up E-PUCH physical resource again in receiving the status report of network side, retransmission sequence number SN is the RLC PDU data of 0-6.
After receiving, network controller abandons these data.
Obviously, above-mentioned processing meeting causes great waste to Internet resources.
For this reason, the method and apparatus of embodiment of the invention high speed downlink packet access dispatching sends at the upstream data that strengthens the user under the CELL_FACH state, at network side to upstream data from this user, no matter from RACH channel or E-DCH channel, unifying ordering handles, the ranking function position that is about to the MAC-es/MAC-is entity of RNC side is placed into MAC-c and (is positioned at the RNC side, handle the RACH channel data) and MAC-e (be positioned at base station side, handle the E-DCH channel data) on, so just can utilize the ranking function of MAC-es entity, the data of RACH channel data and E-DCH channel are unified ordering.
As shown in Figure 3, be the flow chart of the method for embodiment of the invention high speed downlink packet access dispatching, mainly may further comprise the steps:
Step 302 selects upstream data to send the channel type that uses; If select the RACH channel to send data, then execution in step 311; If select the E-DCH channel to send data, then execution in step 321;
Step 311 is encapsulated as MAC PDU on the RACH with MAC-es/is PDU, and sends to network side by RACH corresponding physical channel PRACH;
Step 321 is formed MAC-e/i PDU with MAC-es/is PDU, and the enhancing uplink physical channel E-PUCH by the E-DCH correspondence sends to network side.
Step 323 after RNC receives E-DCH FP Frame, is submitted to the MAC-es/is entity with MAC-es/is PDU in the E-DCH FP Frame and corresponding TSN information; Execution in step 303 then;

1. if select to send data by the RACH channel, then the MAC-es/is entity is selected suitable MAC-es/is PDU size according to the form on the RACH channel, and adds TSN.Also need to add fragmentation state (SS, Segmentation Status) information and length mark L for MAC-is PDU; Then, the MAC-es/is entity is submitted to the MAC-c entity with MAC-es/is PDU, and the MAC-c entity is packaged into the MAC PDU on the RACH channel with MAC-es/is PDU (perhaps MAC-es/is PDU+ length mark L), sends to network side.
Need to prove, can discern this MAC PDU in order to make network side, in embodiments of the present invention, can expand the MAC SDU structure on the existing RACH channel, introduce TSN therein, also need to introduce SS information and length mark L corresponding to MAC-is PDU, as MAC PDU.
As shown in Figure 5, be in the embodiment of the invention corresponding to the MAC PDU form of MAC-es, wherein:
TCTF is the destination channel type field, the MAC-es/is PDU content of expression carrying;
The UE-id type, the type of expression UE sign is specially E-RNTI (Radio Network Temporary Identifier of enhancing) type;
UE-ID, the sign of expression UE is specially E-RNTI;
C/T, presentation logic channel number/type.
Wherein, comprise TSN and MAC-es SDU in the MAC-es PDU form.
